Title: Photomagnetic recording and reproducing device
Inventor: NIIHARA TOSHIO
IPC: G11B11/10
Filed: 1985-03-20
Abstract: PURPOSE:To compensate the variance of the recording sensitivity due to the variance of the ambient temperature by providing a temperature detector which detects the ambient temperature and a laser control part which controls the intensity of the output light of a laser in accordance with the detected temperature. CONSTITUTION:When the recording operation affected most by the variance of the ambient temperature of a disc 6 out of recording, reproducing, and erasing operations is performed, the ambient temperature is detected by a temperature detector 17 using a thermocouple and is sent to a laser control part 18, and the output of a laser driving part 15 is so controlled that a recording laser light intensity 19 corresponding to the ambient temperature is obtained. A recording medium 7 irradiated with the laset light at the recording time is heated locally to a prescribed temperature independently of the ambient temperature. Thus, the variance of the recording sensitivity due to the variance of the ambient temperature is compensated to eliminate the difference of size among recording bits.

Filed: 1994-02-28
Abstract: PURPOSE:To improve output of an engine by way of heightening combustion efficiency by communicatively connecting the other opening end of an air intake passage to an air intake port of the engine through a water removing mechanism. CONSTITUTION:When outside air is introduced into a first air room part 9a of an air room 9 from outside through an outside air introduction port 6 of a hull 1, the outside air in the first air room part 9a is introduced to a second air room part 9b through an opening part 11 of a wall member 10, and thereafter it is introduced into the inside of an outside air introduction pipe 19 through an opening end 19a. The outside air introduced to the outside air introduction pipe 19 is supplied to an air intake port 18 of a carburetor 14 through a separator 20 and a silencer/flame arrester part 21. At this time, when the outside air and water are not separated inside of the air room 9, water enters the outside air introduction pipe 19 with the outside air and flows into the separator 20, the outside air and water are separated by the separator 20. Consequently, only the outside air from which water is separated is supplied to the air intake port 18 of the carburetor 14, and combustion efficiency is improved.

Title: Eliminating method for coating film of reinforced optical fiber
Inventor: KOUMURA YUKIO
IPC: H02G1/12
Filed: 1981-04-13
Abstract: PURPOSE:To prevent the break from the cut end face in the axial direction, by irradiating a laser beam, where the focus is so adjusted that the laser beam does not reach an internal optical fiber, only to a reinforced plastic player on the outside circumference of the optical fiber and cutting and separating the coating film.

IPC: G02B6/25
Filed: 1982-04-03
Abstract: PURPOSE:To obtain a connecting method with less transmission loss by polishing an end surface of a single mode optical fiber at right angle to its axial core and joining the end surfaces. CONSTITUTION:The coating 2 of the optical fiber 1 is stripped off at an end part and the fiber is then inserted into the hole 3 of an optical fiber holding member 4 to fix the following coating part 2 to a coating fixing base 6. At this time, the optical fiber is fixed while flexed in the middle and the end is pressed against a polishing board 7 by its own elastic force. The thickness (t) of the optical fiber holding member 4 is found from an equiation 1 by determining the diameter difference D-d between the hole 3 and optical fiber 1. For this purpose, while the equation I holds for the diameter D of the hole 3 and the thickness (t) of the optical fiber holding member 4, the cut optical fiber 1 is polished to finish the end surface of the optical fiber 1 at a <1 deg. angle of cutting, i.e. nearly at right angle to the axis.

Filed: 1985-03-22
Abstract: PURPOSE:To improve the access capacity of a disk device by setting a reference cylinder at a place near the intermediate circumference of a data zone and therefore halving the maximum access time between the reference cylinder and the cylinder that is set at the most distant place. CONSTITUTION:The zones IDATA5, ODATA16 and ODATA27 are provided on a servo surface 2 opposite to the zone where the data 9 is written on a data surface 3. While zones IGB4 and OGB8 are set at the inside and outside of those said zones on the surface 2. If a magnetic head exists in the zone IDATA5, the head receiving a re-zero instruction starts to move to the outer circumference and then to the inner circumference after detection of the zone ODATA27. Then the head is slowed down while traveling the zone ODATA16 and stopped at the most outer circumference of the IDATA5. Thus, a re-zero action is through with the most outer circumferencial cylinder defined as a reference one.

Title: Orienting method and orienting device for oriented film
Inventor: HIOKI TOSHIFUMI
IPC: G02F1/1337
Filed: 1994-03-28
Abstract: PURPOSE:To uniformly orient polymer chains without adding an orverload on an oriented film and to obtain good orientation of the oriented film by raising the temp. of the oriented film and rubbing the surface of the film while the temp. is being raised. CONSTITUTION:In this device, a substrate 10 is heated in two stages with first and second hot plates 5a, 5b in an entrance terminal zone B to raise the temp. of the substrate 10 and the oriented film 11. After standby time has passed, the substrate is carried to a rubbing zone A where the film 11 is rubbed. In this method, although the oriented film 11 comprising a polymer material such as polyimide, has high film hardness and poor flexibility at room temp., the oriented film 11 on the substrate 10 carried in the rubbing zone A has lower film hardness because the temp. of the film is raised by heating the substrate 10 in the terminal zone B. Therefore, by only lightly rubbing the surface of the oriented film 11 with a rubbing roller 3, the polymer chains can be oriented in the rubbing direction.
